Abstract:With the rise of offshore oil development projects，drilling platforms in sea towage operations have been developed rapidly，and towing operation has attracted more concern and attention. In this paper，the composition and working principle of rig towing and ship dynamic monitoring system are discussed in detail, reasonable proposals of implementing each functional unit are put forward. The application of the system has greatly improved the modern management of the offshore drilling platform and the ship, and realized high efficiency and safety of towing vessel mobilization. It can provide a reference to the related industries.
